drywall behind tile in shower

I have a 6 yr old home. The tile behind the shower directly above the shower pan and grout have started coming off. It appears that the drywall is NOT green rock and looks as if mildew is all over it. Should I take it all down and replace the drywall w/green rock?

Cement board, wonder board, durorock is the only way to go. be sure to remove enough tile to get a good the cement board nailed to the wall without nailing threw the shower pan, also check to make sure someone else didnt nail it either. put the smooth side out and good luck...
